I wanted to switch to compressed air but there are so many brands out there I'm wondering which one to get? I can only have a tank that has a pressure of up to 3000 psi and no more. My local dive shop isn't able to fill the 4500 psi tanks. They said not to get carbon fiber because it can easy burst if bumped or hit. Tanks are made of many different materials like steel, carbon fiber, aluminum and fiber glass. What are the advantages/disadvantages of the different materials. I found a fiber glass tank that can run on C02 or compressed air. Would that be safe? I have a Tippmann A-5 and I want to get a tank that will provide the maximum amout of shots with minimum size. Keep in mind I will be using an air remote. I realize air tanks are very expensive even so let me know what is really good no matter the price.
